Landscape photography, in my opinion, is one of the hardest to present.
Wildlife is easy as most viewers just pay attention to the animal. Portraiture, the scene tends to be setup by the photographer.
Landscape ... well you get what you see ... and most often you see something that says, yeah take a picture, then you realized all this other junk in the shot that you didn't pay attention to.
I find that their is more juggling involved in getting a good/great landscape image ... many many things have to play/compliment eachother. Often times I see something that looks cool, then I have to stop and see what else is there ... or what else could be there at a different time of day ... or even day of the year.
Yes, it ain't easy.
When you do find a scene that looks ok, look around. Take a shot, then come back at a different time when the lighting is different ... or even contemplate what it looks like in a different season, then take that image.
When I frequent someplace often enough I "know" when it is time to take it's picture.
Blah, blah ... just admit you ain't going to be a landscape photographer in a day, and just keep shooting away.
Oh, and Derrel mentioned focal lengths ... Landscapes can be shot with any focal length, not just the wide that tends to be shown most of the time.
Just a mental trick ... look at everything in the scene except the thing that attracted your attention, then see if it works ... if not, change your view point, or change up focal length, start walking around with one eye closed.
